/**
 * In some cases, some frameworks and libraries use some binary codes tech too. From the community feedback, some of them have compatible issues with byte-buddy core, which trigger "Can't resolve type
 * description" exception.
 * <p>
 * So I build this protective shield by a nested matcher. When the origin matcher(s) can't resolve the type, the SkyWalking agent ignores this types.
 * <p>
 * Notice: this ignore mechanism may miss some instrumentations, but at most cases, it's same. If missing happens, please pay attention to the WARNING logs.
